Of Ephyra (town), Fiery (pyrha)
EPHYRA was the eponymous Okeanid-nymph of the town of Ephyra--better known as Korinthos (Corinth)--on the Isthmos in southern Greece. She was the wife or daughter of the Titan Epimetheus. She probably presided over her namesake town's water supply.
Ephyra was surely identified with Pyrrha--the daughter of Epimetheus and wife of Deukalion.
E′PHYRA (Ephura), a daughter of Oceanus, from whom Ephyraea, the ancient name of Corinth was derived. (Paus. ii. 1. § 1; Virg. Georg. iv. 343.)
